STOVE-G RATE.

SPECIFICATION forming part of Letters Patent N o. 349,237, dated September 14, 1886. Application filed October 27, 1885. Serial No. 181,096. (No model.) Patented in Canada June 5, 1885, No. 21,809.

To all whom it may concern:

Be it known that I, HORACE CARLETON SNOW, of Winnipeg, in the county of Selkirk, in the Province of Manitoba, in the Dominion of Canada, have invented certain new and useful Improvements in Stove-Crates; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention consists in the combination of two annular grates having coinciding radiallydisposed bars, and handles to coincide when the bars intervene, the upper grate provided withprongs on the inner and outer peripheries and each grate having an independent -annular movement, or both a combined movement, whereby the grates can be relatively adj usted to close thebottom, to either exclude draft and retain small c0al,or opened to permit free draft and allow large elinkers to pass through, the

'prongs on the upper section being to clean away clinkers which may impede the movement of the grate.

My grate is particularly designed for use lwith the form of Ventilating stove shown in my application, No. 172, 7 79, tiled July 27, 1885.

VFigure 1 is a perspective view ofniy improved grate, the parts in relative position, whereby the radial bars coincide; and Fig. 2 is a plan view of the same, showing the handles coinciding, whereby the grate-bars arein i11- termediate position.

The lower section of the grater is formed of inner and outer annular rims, 2 3, connected by radial bars 4, and provided with a handle, A.

A is the circular opening through the. center of the grate, through which passes the ventilating-tube D of a stove, said tube being shown in Fig. 1 in dotted lines. The lower section of the grate rests on bearings within the stove, and has a reciprocating circular motion about the tube when shaken by the handle.

B is the upper section of the grate, bearing iiatwisc on the lower section, and having annular rims 2 3* and radially-disposed bars 4, corresponding to the lower section of the grate, and a handle, B', which 'overrides the lower handle, so that when the two handles coincide shown in Fig. 1, the openness ofthe grate-bars will permit clinkers to pass, and afford a free draft through the fire. The outer edge of the grate section B and the inner edge of the same are provided with standing prongs C C', to break away from the fire-pot any accumulation of clinkers, &c., which may impede the shaking of the grate.

I am aware that grates have been constructed having prongs to break away clinkers adhering to the wall of the {ire-pot. I am aware that a grate is shown in Patent No. 168,772, wherein the grate has a central valve to dump ashes through the grate, and a ring supporting the grate has prongs to keep the fire clean of ashes near the outer periphery of the grate; but such is not my invention. I am further aware that a grate is shown in Patent No. 119,535, in which a bottom or gratevto the irechamber is formed of two sections, one above the other, and adjustable to make an open or close bottom. I am further aware that a grate having upwardly-proj ecting points over its area is shown in Patent No. 258, 328 5 but the function of such points is not to clear away clinkers.

I claim as my invention.

The combination of the upper grate-section having inner and outerannular rims provided with prongs connected by radial bars and provided with a handle, and a lower grateseetion having rims and bars coinciding with the rims and bars of the upper section and provided with a handle relatively placed, whereby the handles will coincide when the grate-bars relatively intervene, as set forth, for the purpose described.

HORACE C. SNOW.
